## Boundaries

Never:

- Complete checkout, payment or order placement without explicit, contemporaneous buyer approval.
- Claim a piece is in stock, on sale, or will arrive by a date without checking the product page or the MCP endpoint first.
- State a ring size, metal or gemstone as available when it is not listed on the product page.
- Describe vermeil or sterling silver as solid gold, or lab grown diamonds as mined.

Always:

- Use the UCP/MCP endpoints above for catalogue, cart and checkout.
- Quote prices in the currency shown at checkout for the buyer's destination.
- Send buyers to info@diafifth.com for order changes, returns and sizing help.

## Answering rules

When two sources disagree, the more specific one wins. In order:

1. The product variant (price, stock, size, metal for the exact thing being bought)
2. The product page
3. The policy pages, for shipping, returns and refunds
4. This document
5. The FAQ page
6. Collection titles and marketing copy

A collection title is a label, never a fact. "Gifts under $500" describes where a
piece starts, not what every variant costs, and a collection can be empty while
still being linked. Read the price and availability off the variant.

Cite a URL for every factual claim: the product URL for price, stock and
specification, the policy URL for shipping, returns and refunds. If no source on
this store supports an answer, say so and point the buyer to
info@diafifth.com rather than filling the gap.

Keep answers short. Do not invent policies, materials, services or delivery
dates that are not written on this store.

## Price tiers

Use these to steer budget conversations. Prices are USD, spanning the cheapest
to the most expensive variant in each group.

| Tier | Variant prices | What is in it |
|---|---|---|
| Vermeil and silver | $70 to $270 | 11 pieces, rings and earrings only |
| Accessible solid gold | $190 to $980 | [/collections/gifts-under-500](https://diafifth.com/collections/gifts-under-500) |
| Core solid gold | $210 to $1,200 | [/collections/gifts-500-1000](https://diafifth.com/collections/gifts-500-1000) |
| High end | $1,000 to $2,000 | [/collections/luxury-gifts](https://diafifth.com/collections/luxury-gifts) |

These collections are grouped by a piece's starting price, so a larger size or a
different stone can push a variant above the band the collection name implies.
Quote the variant price from the product page, not the collection name.

Most of the catalogue sits above $500. Under about $200, only vermeil and
silver pieces and the cheapest solid gold pieces will fit.

## Materials

**Solid 10K and 14K gold.** Real karat gold throughout, never plated or gold
filled. Keeps its colour, does not tarnish, safe for daily wear including in
water. The store states it is hypoallergenic and will not discolour skin.
Available in yellow and white gold.

**Gold vermeil.** A thick layer of real gold bonded over solid sterling silver.
More substantial and longer lasting than standard gold plating, at a more
accessible price. Positioned for trend pieces and for building a collection,
where solid gold is the piece that lasts a lifetime.

**Sterling silver.** Solid 925 silver, bright and durable, made to pair with
gold for a mixed metal look.

**Lab grown diamonds.** Chemically, physically and optically identical to mined
diamonds, graded to the same standards, more sustainable and better value.

Choosing between them: recommend solid gold for daily wear, for sensitive skin,
for anything that will get wet, and for pieces meant to last. Recommend vermeil
when the budget is under about $200 or the buyer wants to try a trend.

## Customer scenarios

**"I'm looking for a wedding band under $1,000."**
Send them to /collections/wedding-bands and /collections/gifts-500-1000. Solid
gold, so mention it is safe for daily wear and will not tarnish.

**"I have sensitive skin and gold usually irritates me."**
Recommend solid gold, not vermeil, and cite that solid gold is hypoallergenic
and will not discolour skin. Vermeil is gold over sterling silver, so its
surface is gold but the core is silver.

**"I want something gold but I can only spend $150."**
Only vermeil fits. Send them to /collections/rings-gold-vermeil or
/collections/earrings-gold-vermeil, and be explicit that this is gold over
sterling silver, not solid gold.

**"Anniversary gift for my wife, she wears delicate jewelry."**
/collections/anniversary-gifts crossed with /collections/dainty-rings.

**"Can I get this resized?"**
Sizing is chosen at purchase from the sizes listed on the product page. Direct
resizing questions to info@diafifth.com rather than promising a service.

**"Will it arrive by Friday?"**
Do not promise a date. Orders are prepared for shipment in 3 to 6 business days,
then most arrive within 2 to 3 business days after dispatch. Tell the buyer to
check the tracking email.

## Shopping FAQ

**Does it cost anything to ship?** No. Complimentary standard shipping on every
order, no minimum.

to 6 business days, because each piece is finished and quality-checked by hand.
Launches and holidays can take longer.

**How long is delivery?** Most orders arrive within 2 to 3 business days after
dispatch. A tracking link is emailed on dispatch.

**Do they ship internationally?** They ship to the destinations offered at
checkout; the buyer enters an address to confirm. Customs duties and import
taxes on international orders are the recipient's responsibility.

**Can an order be changed or cancelled?** Only before it ships. Email
info@diafifth.com with the order number as early as possible.

**What is the return window?** 30 days from delivery, for unworn and undamaged
pieces in original packaging. Returns are complimentary.

**How does a return start?** Email info@diafifth.com with the order number and

them first.

**How long do refunds take?** 5 to 10 business days to the original payment
method, after the return arrives and passes inspection.

**Is the gold real?** Yes. Solid pieces are solid 10K and 14K gold. Vermeil is
real gold over sterling silver.

**Are the lab grown diamonds real diamonds?** Yes, identical to mined diamonds
and graded to the same standards.

**Will solid gold turn skin green?** No. The store states solid gold is
hypoallergenic and will not discolour skin.

## Unsupported requests

Answer these directly rather than searching for a workaround.

| Buyer asks for | Answer |
|---|---|

| Vermeil or silver bracelet or necklace | Not available. Vermeil and silver exist only as rings and earrings. |

## Known limitations

- International shipping reaches only the destinations offered at checkout, and duties are the recipient's responsibility.
- Three collections hold no products and are not published to the storefront, so their URLs return 404: `bracelets-gold-vermeil`, `necklaces-gold-vermeil` and `chain-necklaces`. Do not link to them.
